ADDING-SECTOR-RESTORING MIECIHANISM.

Application filed November present invention is applicable totabulatorprinters of the character shown in U; S. Letters Patent No.1,245,502, to avhich reference can be had for details of the functionand operation ofthe adding sectors. In this patented construction theadding sectors are set in position when a carry is necessary, by theaccumulator wheels-upon the return stroke of thesectorsafter eachprinting operation set-up, and then must be cleared to zero before thetotal taking stroke takes place when the sectors roll out theaccumulation on the printing set-up stroke In machines of the characterin use heretofore thisclearing or resetting of the adding sectors tozero takes place under control of a space card which must run throughthe analyzing unit ahead of the total card. g V.

Some of the objects of the present lnvention are to provide animprovedmeans for clearing and restoring adding sectors of, tabulating orkindred machines to normal or zero position; to provide means for takinga total automatically anddirectly following the last card of a group tobe added; to provide means for eliminating the use of an extra card fortotal taking purposes; to' provide means whereby the number of cardcycles is reduced,

in the addition of and total taking'of perforated data on agroup ofcards; and toyprovide other improvements as will hereinafter appear. i

In the accompanying drawings Fig. 1 represents a detail in sideelevation, with parts broken away, of anadding sector and its adjunctshaving a sector clearing and total takingmiechanism embodying one formof the present invention; Fig. 2 represents a sectional detail of anautomatic latch control for a cam operated part; Fig. 3 representsafragmentary elevation of an adding sector-in zero position and theoperating parts for returning the sector to such position; Fig. 4represents a similar elevation to Fig. 3 with-an adding sector inposition; Fig. 5 represents afragmentary portion of the machine in partsection showing the position of the parts with the total pin inanalyzing 24, 1925., Serial No. 71,192.

relation to the total card; Fig. 6 represents a perspectlve of the totaloperating lever castmg; and'Fig. 7 represents adetail in plan of thecontrol cams.

Referring to the drawings, one form of the present invention is shownapplied to an adding sector 10 which forms one of a series of sectors ina unit for setting type sectors in pr nting position according toperforat ons in record cards which control the action of the sectors 10.Each sector 10 is mounted for rocking movement on a pivot 11 andcontrols the position of its type seetor 12 so that the type 13 arerespectively located in printing position with respect to the paper l4and platen 15; Connection between'eachadding sector 10 and its type sector 12 1s byway ofa lost motion slot 16 and a pin 17, while a spring 18is normally under tension to project both sectors toward the typesetting position. A spring 20 is stretched between the two sectors sothatthetype' sector 12 is held pressed to its initial position While theadding sector 10 is under tension to complete its carry operation andcome to rest, when released for carry, one tooth behind the zero po-.sition. lVhen such adding sector 10 is not to function for a carryoperation, it is held and limited in its return movement by a pin 21laterally projecting from the sector 10 and abutting the end of the hook22 of a bar stop 23 which is provided with a totaling abutment spur 24located in the path of movementof the carry lug 25 on the accumulatorwheel 26 of the next lower order. Thus, when the accumulator wheel ofthe next lower order reaches the position to carry over, its lug 25engagesthe spur 24 of the adjacent adding sector of higher order andlifts the bar stop 23 so that the sector pin 21 registers with the slotportion of the hook 22. This allows the adding sector 10 to travel onetooth farther than normally and so actuate the accumulator wheel whichit controls.

The adding sectors'are each normally held in zero position by ,a shutter27 having a zero stop 28 in the path of the sector heel 29', and theshuttersare released for operation by rocking them to one side as wellunderstood in the art.

In order to restore all of the adding sectors 10 to zero position priorto the total taking cycle, a bail 30 (Figs. 1, 3 and 4), is

arranged transversely of the machine and is carried at its ends by rockarms 31 so that its path of movementintercepts all of the sectorswhichare in carry position and its length of travel is such as to bringsuch sectors back to zero position abutting the shutter zero stops'28and releasing the bar stop 23 so that it drops to bring its hookend intore'gisterwith the pin 21. 'The arms 31 are journalled on suitablestandards 32 (only one being shown) and an operating rod3 3 pivotedthereto is pivotally connected at 3410 one end of an operating lever 35,which is s pivoted to a bracket 36, (Fig. 3), and has its other endprovided with a roller 37 traveling in a cam groove 38 of an actuatingcam mounted on the action shaft 41. The bracket 36 also serves as a'pivotal support for a-rock lever 42, the function of which willpresently appear. Thus at the end of a group tabulation the initial stepin the total taking cycle brings the cam 40 to a position cumulatorwheels of the several units are .tllIOWIl into and out 'of mesh with thesectors 10, 'is positively shifted to unmeshing position by the rocklever 42 transmitting motion through a link 44 to the cam 43, wherebythe latter is' shifted clockwise, as seen in Fig. 3, to thereby cause'the accumulator wheels to be removed from the sectors 10.

The rock lever 42 is operated only at the time a total is'to be takenand remains idle at other times so that the control cam 43 isautomatically thrown into and out of mesh with the adding sectors by theaction of the accumulator link 45 under the control'of theoscillatingcrank sector cam 46. This intermittent action of the rock lever 42 isefi'ected in the present instance by the provision of a second cam 47keyed to the action shaft 41 and provided with a camgroove 48 facing the free end of the rock lever 42. This end of the rock lever 42 isprovided with a capped bushing 50, '(Fig. 2), which receives a plunger51 normally under pressure .of a

coil spring 52 having a tendency to eject the plunger toward 'the groove48 and with which it is normally'in alinement. -The end of the plunger51is provided with acircumferential groove or shoulder 53 for coactionwith a pivoted latch 54 which is normally held pressed towardsaidlatching groove 53 by a spring 55 stretched between 2. lug 56 on 42.Normally, the latch 54 is held by its spring 55 seated in the groove 53so that the plunger 51 is held out of'the groove of its cam 47 butprovision is made for releasing the latch 54 at the proper time in thegroove 48 and comes under its control to actuate the rock lever 42 atthe-proper time. As soon as the rock lever has completed its controlmovement the plunger 51 is autoniaticallyejected from the cam groove 48by the inclined face of a block 58. (Fig. 1), located in thegroove 48and acting to return the plunger to latching engagement with the latch54. The releasing of the latch 54 from its-plunger 51 takesplace intimed relation by the provision of a link60' connected at one end to thelat-ch'and at its other end to a .bell crank 61 which is pivoted at 62to a fixed part and has its opposite end provided with apin 63.

For operating the bell crank 61 at the proper time in the cycle of totaltaking, the

pin 63 is so located that in total operating po-- cycle of operationsleading up to the total tak- I so that the plunger 51 enters the camsition of a reciprocable link 64 it is in the path of movement of a lug65 fixed to the link 64, and thereforev receives motion transmitted fromthe link 64. The link64 is pivoted at 66 to one arm of a pivoted bellcrank 67 and has bearing lugs 68 at one end to receive a rod 69 which isalso connected to the pivot 66..

This rod 69 passes through a hole 70 in the lower extremity of a totalpin71 and it is the function of this pin 71 to so vary the. position ofthe link 64 as to determine its connection to parts operated thereby.WVhen the total pin 71 moves upward under the action of its spring, itcarries the rod 69 with it, and since the latter is pivoted at 66 and isalso fast to the link 64, the last named will also be swung around thepivot 66 and thus bring the lug'65 to a diflerent position. Motion istransmitted to the bell crank 67 by a roller 7 2 carried by itsoperating arm 73 and riding in a cam groove 74 of a cam 75 on the mainshaft 7 6 of the machine. In addition to causing operation of the bellcrank 61 the reciprocation of the link 64 also-transmits motion to anarm 77 of a casting 78 pivoted upon a shaft 80 and having an arm 81arranged when operated to snap past and be held by a pivoted latch 82which is normally urged toward latching position by a spring 83. Thefree end of the latch 82 has a projecting lug 84 arranged in latchingposition to extendinto the path of a trip 85 carried by the cam 75.-Motion is transmitted to the arm 77 by a pin or lug 8,6 projecting fromthe link 64 and so located as to intercept a pin 87-on the arm 77 ceptthe total taking one, the link 64 reciprocates the lugs 65 and 86 in apath which does is taken, however, the total pin 71 is .re-

stricted in its movement by the punched total card and thereby shiftsthe link 64: so that its lugs 65 and 86 reciprocate to engage therespective pins 63 and 87.

The rocking movement of the casting- 78 is transmitted by an arm 90 anda connecting rod 91 to acrank 92 on the total taking shaft 93;A latchlug9 1 (Eigij) is provided on the arm 81 of the casting 78 for engagementby the latch 82 in order tohold the total shaft 93 in total takingposition for the proper carrying out of the total cycle. lVhen the trip85 on the cam 7 5 picks up the latch 82, the total taking shaft 93 andits associated parts are released for return to initial andidleposition.

In order to restore the sectors following the setting and printingoperations a restoring bar 95 (Figs/1, 3 and 4) is mounted between twoend restoring frames 96 and extends transversely across the front edgesof the type sector arms 97. The frames 96 are pivoted on the pivot 11which also serves as the bearing-support for the type sector arms 97.The movement of the restoring frames 96 takes place through a cam.roller 97 mounted upon one frame 96 and operativcly located in a camslot 98 of a cam member 100 which is pivoted on a rod 101 to swing inthe desired arc to cause the actuation of the r'estoring frame. The camslot 98 is provided with a dwell 102 which causes the proper timedrocking of the restoring bar 95 and also provides for holding thesectors from forward movement for the period when the accumulator wheelgears are disengaged to clear the machine and reengaged to roll out theaccumulation for the total; An operating link 103 connects the cammember 100v with a crank sector 46 fixed to the actuating shaft 105 ofthe machine, the said'sector 46 also serving to rock and control theaccumulator cam l3 as will be understood by reference to U. S. LettersPatent No. 1,388,271 wherein the construction and operation of theaccumulator wheels 26 is-shown and described and need not be hererepeated since this forms no part of the present invention.

In the operation of the machine the printing sectors and associatedparts are operated for n'intins the data by control pins passing throughthe perforated card to position the sectors so that the selected typeare in position to print upon the platen and the recorded amounts areaccumulated for a total by the timed swinging of the crank sector 46 tomove the accumulator wheel gears into mesh with the toothed sectors ontheir return movement and to remove the accumulator wheel gears on theforward stroke of the same toothed sectors. The operation of the cranksector 46 also causes the-restoring frame-to operate in the desiredmanner to bring the printing sectors back to their Zero position. lVhenan accumulator wheel has been rotated to the carry-over'position itslug'25 engages the spur 24 of the bar stop 23 which causes the hook 22to be' raised so that the lug 25 on the adding sector of the next higherorder can move into the slot of the hook and thereby permit the addingsector to travel one tooth farther than under normal conditions so thatthe corresponding accumulator wheel moves one digits distance. It willtherefore be evident that those adding sectors which are in carryposition back of the Zero position must be reset to Zero before thesectors move to roll out the accumulation on the accumulator wheels.

\Vhen a total is to be taken the analyzing unilxcomes into analyzingrelation with respect to the total card which is at the end of the groupbeing tabulated and this total card allows the total pin 71 to moveupward until its collar 71' contacts with the card and in this positionof the total pin the connected recip- .rocable link (34 has been movedto the posilion where the pin 63 is in the path of movement of the linklug 65 and the pin 87 on the arm 77 is also in the path of the lug 86 onthe link 04 and consequently the movement of the link til is transmittedto both the bell crank 01 and to the arm 77, and it will thus be seenthat two (llSl llit'loperations are set into motion by the actuation ofthe link 0%. The operation which shiftsthe arm 77 causes the connectingrod 01 to actuate the total taking shaft 03 to cause the total takingoperation. The shifting of the bell crank (it raises the that it cntcrfsthe cam groove 48 and throws its rock lever -12 under cam control, andas this; .is rocked the accumulator wheel cam 43 is. operated in thedirection to remove the accum-' ulator wheels from meshing engagementwith the adding racks. Operating in timed relation with this removal ofthe accmnulator wheels the cam 10 causes the operating lever 35 to berocked in a clockwise direction to shift the bail 30 counterclockwiseand return the adding sectors to zero position whic thus clears themachine for the total stroke of the adding sectors. The timing of theoperation of the parts is such that the inclined face of the block 53releases the plunger from the cam groove 1-8 so that the accumulatorwheel cam is again free to be operated by its normal controlby the cranksector 10. The crank sector -10 at this part of the cycle is in aposition holding the restoring frame actuating cam in a position to holdthe. seetorsfrom forward movement and they areso held not onlydurtoothed sectors and at this time all of the sec rolling out theaccumulation and bringingthe type into position to print a total.

From the foregoing it will be apparent that the taking of totals by cardcontrolled tabulating machines has been greatly simplified and the cardgroup totals are taken automatically without interposed steps inpreparation for taking the total. By the mechanism of the presentinvention it is now un necessary to provide a clearing card in advanceof the total card and the time heretofore consu qed in properly placingsuch space or clearing cards in the respective groups is tors are readyto make the forward stroke for 4. In a machine of the character stated,

Incidental to thus dispensing with the clearing cards is theelimination of, errors heretofore present due to placing the clearingcards at the wrong place in the group of cards so that the machine iseither cleared -prematurely or the total cycle takes place withoutclearing and an incorrect total results.
